Video Description

OnePlus Watch 3 (affiliate): https://mikeobrienmedia.com/OPWatch3 The Galaxy watch has been a great recommendation for years until last year where the OnePlus watch gave it some competition. I still preferred the Galaxy watch as an everyday android watch but now the OnePlus watch 3 here absolutely destroys the Galaxy watch in a couple categories. So there are several main upgrades to the OnePlus watch 3 that fixed the biggest drawbacks of the OnePlus Watch 2 and strengthened its biggest benefits. so I've been wearing this for about 2.5 weeks now and I only charged it twice. there's also finally a rotating crown which you don't have on the Galaxy watch Ultra or the Galaxy watch 7. Of course, I did a ton of testing so in this video, we’ll talk about the design, dive into the new features, and of course go through some of the accuracy tests I ran. Follow me on social media!

Thank you all for watching! Additional video notes: Rotating crown + button Bottom button - for opening workouts or for ECG 2 colore Emerald Titanium - silver titanium bezel + the only green is on the rubber strap Stainless steel case Stainless steel buckle So actually very little titanium - not making any real difference on weight or durability. - stainless steel is great though Obsidian titanium - same thing but black Strap connection method Display - 1.5” display 2D sapphire crystal glass Peak 2200 nits, as low as 1Hz for battery life IP68 +5ATM - so fine for swimming Their newest phone is weirdly better at IP69. Shouldn’t be an issue since this is allegedly MIL-810H so good for up to 158F - I wore it in a sauna hotter than that but ideally the watch will be cooled by your skin there Health monitoring Multi-dimensional sleep monitoring Wellness score Wrist temperature added 60 second health report - Garmin does this but in 2 minutes 6 key indicators - vascular age, hR, SPO2, Mental wellness, sleep quality, wrist temp ECG analyzer will not be available in the USA - not coming to the US & Canada This was weird though - got mad at me for a low HR when it was 49 Nap detection tested & it works really well! Dual engine architecture - Snapdragon W5 & BES2800 Silicon nanostack battery (as seen in oneplus 13) Now 631mAh vs old 500mAh This alone will destroy most other watches - Expect others to copy!! Apple Watch - 18 hrs Pixel Watch - 24 hrs Galaxy Watch 7 - about 24 hrs Now being that the Pixel Watch, Galaxy Watch, and this are three of the most commonly purchased Android smartwatches here in the US, I’ll be making an in-depth comparison video very soon. Get subscribed if you haven’t already! Usb-C charger Any other charging methods? - no UX TOUR Control tiktok or vertical videos (maybe only YT & TikTok?) Camera control SOS Find my device Google Wallet, Maps, Calendar, and all the google apps you would expect Offline spotify Google Assistant - not branded as Gemini here yet APP TOUR SPEAKER & MIC TEST Bluetooth 5.2 Haptics - ? PROS: Beautiful design Battery life is incredible Rotating crown makes the watch so much more usable Plenty of apps available Video watch faces & customized tiles / widgets Fall detection - yes Overall, a fantastic wearos watch CONS OHealth app is not great ONLY ONE SIZE? Female cycle tracking? - no No ECG in USA No bodyscan like what Galaxy has No mention of aquatouch or glove mode Huge miss for women. It is clear OnePlus wasn’t thinking of women at all when they made this watch. Compatible with iphone? - No (expected)
